BLOW-OUT PATCH.

Application filed February 20, 1926. Serial' No. 89,769,

This invention relates to pneumatic tires and has more particularI reference to a patching means for the shoes thereof whereby small cuts in said shoes may be readily repaired without requiring the vulcauization of the saine.

The primary object of the invention is to provide a patch that may be readily employed for the purpose intended unskilled persons, and that when so attached to the shoe will not readily become disengaged therefrom and is of such construc-v tion as to prevent the pinching of the inner tubebetween the shoe and patch.

Other objects will become apparent as the nature of the invention is better unden stood, the same comprising the novel form of blow out patch hereinafter more fully described, shown in the accompanying drawing, and claimed.

In the drawing` wherein like reference characters indicate corresponding parts throughout the various views:

Figure l is a 'fragmentary elevation of a conventional form of pneumatic tire shoe, with which is associated my improved patch.

Figure 2 is a detail longitudinal section taken substantially upon the line Q-2 of Figure i for more clearly disclosing the construction of the patch.

ll`igure 3 is a full sized view of the patch, one of the strips of fabric composing the same being broken away for more clearlj.7 disclosing` the means whereby said patch may be rigidly secured to the shoe, and

Figure i is an edge elevation of said securing means per se.

flow having particular reference to the drawing, 5 indicates a conventional form of pneumatic tire shoe that has become cut at G.

The patch constructed in accordance with the present invention includes a pair of preferably rectangular shaped strips of rubberized fabric 7 7 that are to be vulcanized in superposed relation as clearly shown in Figures 2 and 3.

Prior to the vulcanization of these strips there `is arranged `intermediate the saine, a

metallic plate 8, the opposite edges of which are provided with various lengthed fingers 9 that are bent downwardly at their outei ends to provide prongs l0 that are passed through one of the strips and that are adapted to be forced through the wall of the tire 5 at opposite sides of the cut 6 after which the saine may be bent over as indicated in Figures l and 2 for preventing` the withdrawal of the prongs from said shoe.

lt will thus be seen that through provision a. patch of this character` the cut 6 in the shoe will be prevented from eX- panding and further ripping the tire, the patch also preventing the tube from becoming pinched between the edges of the cut and the nature of the material formingthe patch being such as to prevent the pinching of the tube between the wall of the shoe 5 and the fabric forming said patch.

Having thus described the invention, what l. clainias new and desire to secure by Letters Patent is i As a new article of manufacture, a blowont patch for tires comprising a laminated patch forming body, composed of a pluof plies of flexible material, and a retaining device comprising a metal stamping interposed between the plies, said stamping being' in the form of a bendable metal plate of general rectangular configuration, said plate having its opposite longitudinal edges tapered from the central portion toward the end, the opposite end portions being formed with substantially i/shaped notches, providing a. multiplicitu of t -shaped tongues, there being two pairs of end tongues, and an intervening pair o central tongues. the central tongues being shorter in length than the end tongues, the extremities of all of said tongues being adapted to be bent at right angles to the body portion of tht plate to provide prongs penetrating one of the plies of said inaterial, and adapted to penetrate the tire casing, to. be secured to the latter.

In testimony whereof I afl-ix my signature.
